Question

我想在x86 Ubuntu 13.04上交叉编译针对ARM Angstrom （BeagleBoard）的 rtl8192cu驱动程序。

交叉编译先决条件：

rtl8192cu driver
跨工具链（CodeSourcery / arm-angstrom-linux-gnueabi）
内核来源

出于这个原因，我在Ubuntu机器上复制了BeagleBoard的内核源代码 usr / src 目录（他们已经在BeagleBoard上编译了，因为我需要重建内核）

运行make进行交叉编译，我收到此错误：

make ARCH=arm CROSS_COMPILE=/home/demetres/CodeSourcery/Sourcery_CodeBench_Lite_for_ARM_GNU_Linux/bin/arm-none-linux-gnueabi- -C /home/demetres/Desktop/ks1 M=/home/demetres/Desktop/rtl3  modules
make[1]: Entering directory `/home/demetres/Desktop/ks1'
  CC [M]  /home/demetres/Desktop/rtl3/core/rtw_cmd.o
/bin/sh: scripts/basic/fixdep: cannot execute binary file
make[2]: *** [/home/demetres/Desktop/rtl3/core/rtw_cmd.o] Error 126
make[1]: *** [_module_/home/demetres/Desktop/rtl3] Error 2
make[1]: Leaving directory `/home/demetres/Desktop/ks1'
make: *** [modules] Error 2

如果我运行file fixdep，我会：

fixdep: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped

这有意义，因为fixdep是内核源代码（在ARM平台上编译）的一部分。

我的查询是： 该程序是否正确，如何解决此错误？

Answer 1

fixdep是一个ARM二进制文件，你试图在x86机器（intel）上运行它。您可能必须重新编译内核资源（只需创建它们）并尝试再次交叉编译。

ARM的交叉编译内核模块
